The asdcplib library is a set of objects that offer
simplified access to files conforming to the sound and
picture track file formats developed by the SMPTE Working
-Group DC28.20.
+Group DC28.20 (now TC 21DC).
-This work was originally funded by Digital Cinema
-Initiatives, LLC (DCI). Subsequent efforts have been funded
-by Deluxe Laboratories, Doremi Labs, CineCert LLC, Avica
-Technology and others.
+Recently, support has also been added for SMPTE draft ST
+2067-5 "IMF Essence Component", AKA "AS-02". This code was
+donated by Fraunhofer IIS. It carries additional copyright
+information which should be listed whenever you link the
+AS-02 elements of the library. Please look at the top of
+the AS-02 files to see this copyright information.
+
+AS-02 support is carried in separate object modules, so
+unless you #include <AS_02.h> and link libas-02.so you are
+still using plain old asdcp.

Design Notes
This library is intended (but of course not limited) for
-use by developers of commercial D-Cinema products. It is
-designed to be easily integrated into a wide variety of
-development environments. Commercial users are strongly
-urged to use static linking (at least where you use this
-library) to prevent malicious in-field replacement of
+use by developers of commercial D-Cinema products (and now
+IMF!). It is designed to be easily integrated into a wide
+variety of development environments. Commercial users are
+strongly urged to use static linking (at least where you use
+this library) to prevent malicious in-field replacement of
critical system modules. This recommendation should be
considered wherever Open Source or Free software is being
used in conjunction with critical security parameters, such
implementations of the ASDCP:: objects which provide those
services.
-AS_DCP.h contains the entire API. You do not need to read
-any of the other files, except maybe asdcp-test.cpp which
-contains detailed usage examples of each of the API's
-services. The KM_* files may be of interest for general
-development support, but may be ignored if all you want
-is simple AS-DCP support.

Build Instructions
this natively, an "nmake" build file and instructions can be found
in the win32 subdirectory.
-OpenSSL is also required, and the most recent version of v0.9.8
-is recommended. See http://www.openssl.org/ for more information
-and download instructions.
+OpenSSL is also required, any recent version should be fine. See
+http://www.openssl.org/ for more information and download instructions.
Optional support for writing Timed Text Track Files is supported by
either Xerces-C or Expat. See http://xerces.apache.org/xerces-c/ or
To configure and build, type './configure' followed by 'make'. There
are several test targets on the POSIX side, but you need to assemble
-a set of test files to use them.

I have tested this build on win32, Linux, OpenBSD, and Darwin
platforms. Others may work as well.
Utilities
-asdcp-test - Writes, reads and verifies AS-DCP (MXF) track files.
+asdcp-test - Writes, reads and verifies AS-DCP (MXF) track files.
+
+asdcp-wrap - Writes AS-DCP (MXF) track files.
+
+asdcp-unwrap - Extracts essence from AS-DCP (MXF) track files.
+
+asdcp-info - Displays information about AS-DCP (MXF) track files.
+
+asdcp-util - Calculates digests and generates random numbers and UUIDs.
+
+as-02-wrap - Writes AS-02 Essence Component files.
+
+as-02-unwrap - Extracts essence from AS-02 Essence Component files.
kmfilegen - Writes and verifies large files using a platform-
independent format. Use it to test issues related to large files.
Documentation
-The API documentation is mostly in AS_DCP.h. Read that file for
-a detailed description of the library's capabilities. Read
-asdcp-test.cpp for library usage examples. The command-line
-utilities all respond to -h.

Change History
-2012-02-03 - bug fixes 1.9.44d
+
+2013-xx-xx - enhancements, bug fixes 2.0.x
+ o fixed a bug that caused blackwave to only produce 96kHz WAV files.
+ (thanks to Stephane W)
+
+2013-07-02 - IMF/AS-02 support, bug fixes 2.0.0
+ o Massive refactoring of internals to allow easier implementation
+ of AS-02. Some API changes were made as well (note that
+ OPAtomHeader is now OP1aHeader and RIP is no longer part of the
+ OP1aHeader.) If you are using this project as a library (and
+ especially if you are keeping patches against it) PLEASE TAKE
+ TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
+ YOUR RELEASE PATH.
+ o Final integration of Fraunhoffer IIS code contribution. AS-02
+ files are now fully supported with some TODOs and one major
+ exception: LEAD indexes are not supported by the MXF writers
+ and interlace images are not yet supported.
+ o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
+ that this project is still in the early stages of interop testing
+ so errors are likely present and don't expect any server to
+ understand this feature.
+
+2013-07-01 - Bug fixes, enhancements 1.12.50
+ o Fixed missing return statement in ArchivableString::ArchiveLength
+ (thanks to both Kristof Provost and Franck Chopin)
+ o Fixed broken sample alignment in RF64Writer (thanks to Dolby)

+
+
+2013-04-12 - Dolby Atmos support and more audio labels 1.11.49
+ o Significant code contribution from Dolby Laboratories to add
+ support for generic data track files as proposed in ST 21DC
+ and also Dolby Atmos track file support as a specialization.
+ o Added Dolby-contributed code to support generating the external
+ sync signal for d-cinema as proposed in ST 21DC.
+ o Added Dolby-contributed code to support RF64 WAVE files.
+ o Fixed UL error in ST 429-5 DM encoding (contributed by Dolby).
+ o Added ULs for ST 428-12 and Amd. 429-2 2013. Please check!
+
+
+2013-02-20 - bug fixes, enhancements 1.10.48
+ o Refactored internals of the AS-DCP file readers. While no
+ changes in behavior are intended, users are cautioned to test
+ thouroughly before use in production.
+ o Fixed a bug in ReadAncillaryResource that was causing bogus HMAC
+ failures when reading resources from a file.
+ o Fixed premature-release bug in the Expat version of the XML parser.
+ Thanks to Carsten Feldheim (IIS) for the tip.
+ o Fixed -W option in asdcp-unwrap. Thanks to RGB.
+ o Added P-HFR support to asdcp-wrap (see URL for details:
+ http://isdcf.com/papers/ISDCF-HighFrameRate-DCP.pdf).
+ o Added support for SMPTE ST 428-21 "Archival Frame Rates".
+ o Added -P option to asdcp-wrap (inserts arbitrary UL into the
+ PictureEssenceCoding property when wrapping JP2K files.)
+ o Added support for 96 kHz files to blackwave.
+ o Added new path and string manglers to Kumu.
+ o Updated MCA ULs (I warned you...). Again please take some
+ time to proof this work against ST 477-4 including the latest
+ drafts of the registries.
+ Changed the version byte (8 0f 16) to 0x0e:
+ MCALabelSubDescriptor
+ AudioChannelLabelSubDescriptor
+ SoundfieldGroupLabelSubDescriptor
+ GroupOfSoundfieldGroupsLabelSubDescriptor
+ GroupOfSoundfieldGroupsLinkID

+ MCATitleVersion
+ MCATitleSubVersion
+ MCAEpisode
+ MCAAudioContentKind
+ MCAAudioElementKind
+
+
+2012-08-07 - bug fix, 1.10.46
+ o Added missing zero-initializers to time values when parsing a
+ timestamp string (in the case where the optional [Thh:mm.[:ss]]
+ syntax is not present in an encoded string).
+
+2012-03-06 - bug fixes, enhancements 1.9.45
+ o Removed ASDCP::Timestamp, all items that were of that class are now
+ of class Kumu::Timestamp
+ o Refactored Kumu::Timestamp to use KM_tai for internal representation
+ (replaced public Y M D, h, m, s variables)
+ o Refactored Kumu::Timestamp to use KM_tai for WIN32 builds
+ o Added UTC offset awareness to Kumu::Timestamp
+ o Replaced "long GetSecondsSinceEpoch(void) const" with
+ "ui64_t GetCTime() const"
o Corrected UL version segment in "7.1 DS" and "WTF" audio format
labels (corresponds with publication of ST 429-2:2011).
o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
o ST 429-5 files have corrected ULs for DCTimedTextDescriptor and
GenericStream DataElement. Files made with previous versions of
the library are incompatible with this and future versions.
- o Fixed File Package TrackNumber values. Thanks to Sankar.
+ o Fixed File Package TrackNumber values. Th
+anks to Sankar.
o Added edit rate constants to AS_DCP.h (25, 30, 50, 60).
o Changed AudioDescriptor "SampleRate" element name to "EditRate"
to make it consistent with the other types.
